Still playing around with this. The biggest surprise is how quiet it is. Even at highest settings it doesn't make a racket nor is there a sense it can be felt or heard on the floor below. It's perfect for an apartment building and doesn't even need the special pads others reference if you have it on carpet. My remote was somehow dead, and owner Jay immediately replaced it and has been ultra-available answering questions. Looking forward to seeing what it can do to strengthen my back, hips, and all else. Was impressed by the full disclosures of the website and obvious efforts to create a top-notch product with fewer moving parts and least likely to break, which is the leitmotif of other brands with bogus warranties that aren't being honored. The vibrations are sufficiently intense at the high settings. It's important to get the exercises just right because the slightest change in position can make all the difference. Videos online around the Internet also showing the range of how these devices may be used, the exercises that can be done; I saved several to a Youtube channel playlist and whip through them on an Ipad sitting on a dining room table I use as a kind of barre for some of the deeper work. Well places and proportioned grooves on the perimeter of the platform also enhance comfort for very direct-contact vibration of the back or, say, the inner thighs. You cannot beat the price (got mine in a "Holiday sale" around Black Friday). But also I know from the reviews of others that if something goes wrong, Jay himself will not hesitate to rectify things as he takes a personal pride in this product. It is also noteworthy that you can program the machine to stay on at 20 minutes a pop which is better than other brands.
